2 ripe bananas, mashed
1 cup natural peanut butter
2 cups rolled oats
1/4 cup honey or maple syrup (optional, for extra sweetness)
1 tsp vanilla extract
1/2 tsp cinnamon
1/4 tsp salt
Optional: 1/3 to 1/2 cup chocolate chips, raisins, chopped nuts, flaxseeds, or shredded coconut
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
In a large bowl, mash the bananas until smooth.
Stir in the peanut butter, honey or maple syrup, and vanilla extract until well combined.
Add the oats, cinnamon, and salt. Mix thoroughly.
Fold in any optional mix-ins like chocolate chips or nuts.
Spread the mixture evenly in the prepared baking pan and press it down firmly with a spatula or spoon.
Bake for 20–25 minutes, or until the edges are golden and the center is set.
Allow the bars to cool completely in the pan, then slice into squares or rectangles.
Store in an airtight container at room temperature for up to 3 days, in the fridge for up to a week, or freeze for up to 3 months.
For a vegan version, use maple syrup and vegan chocolate chips.
Use certified gluten-free oats for a gluten-free adaptation.
These bars can also be made no-bake by chilling them in the fridge for 2–3 hours instead of baking.
